Enzymes are a type of macromolecule that belong to the class of proteins, which are large, complex molecules fundamental to both biological and chemical processes. These enzymes are responsible for breaking down various macromolecules, such as carbohydrates, sugars, and starch. The four major classes of biological macromolecules are carbohydrates, lipids, proteins, and nucleic acids.
Induced fit occurs when a substrate binds to an enzyme on the active site, causing the enzyme to change its shape to allow the substrate to be broken down. Enzymes are essential in catalyzing biochemical reactions and are responsible for the structure and function of these molecules. They are synthesized via a process called protein translation, which occurs at the site of binding to the active site.
The four major classes of biological macromolecules are carbohydrates, proteins, carbohydrates, nucleic acids, and lipids. Carbohydrates, such as fats and oil, belong to the four macromolecules of life. Enzymes belong to the class of proteins, which are distinct from carbohydrates, nucleic acids, and lipids.
In summary, enzymes are essential in breaking down various macromolecules, including carbohydrates, lipids, and nucleic acids. They play a crucial role in the formation of cells and perform a wide array of functions. Enzymes are a key component of these complex molecules, and their unique structure and specific functions make them essential for the functioning of cells.

What group of macromolecules do enzymes in our bodies belong to?
The majority of enzymes are proteins, though some are Ribonucleic acid (RNA) molecules. RNA molecules translate information from DNA and create proteins.
Each cell contains thousands of enzymes, providing specific help throughout the body.
Enzymes help with the chemical reactions that keep a person alive and well. For example, they perform a necessary function for metabolism, the process of breaking down food and drink into energy.
Enzymes speed up (catalyze) chemical reactions in cells. More specifically, they lower the threshold necessary to start the intended reaction. They do this by binding to another substance known as a substrate.
What group do enzymes belong to?
Complete answer: All enzymes belong to a chemical group of molecules known as Proteins. These are molecules that have a functional unit known as Amino acids. Amino acids have two functional groups in each of them, an amino $–NH_2$ and an acid $–COOH$ group. A number of amino acids are linked to each other to form a protein molecule and the bond between adjacent amino acids is known as a peptide bond. The chain of amino acids is known as a polypeptide chain.
Enzymes are functional when the amino acids are linked to form a three-dimensional structure. Enzyme mediated catalysis is highly specific. When this structure gets distorted in presence of high temperature the enzymes become non-functional or denatured. The major functions of enzymes are in DNA replication and repair and also in the process of transcription. The molecules on which enzymes act are known as substrates and the molecules formed as a result are known as products.
Note: The structure of proteins can be distinguished as four types. Primary, secondary, tertiary, and quinary. The primary structure is composed of simple amino acid chains. Secondary structure is of two types: alpha-helix and beta-pleated, where peptide chains are folded which are stabilized by hydrogen bonds. Further folding of secondary structure results in tertiary structure forming a protein complex.
What are the four macromolecules?
11. 1 Introduction: The Four Major Macromolecules. Within all lifeforms on Earth, from the tiniest bacterium to the giant sperm whale, there are four major classes of organic macromolecules that are always found and are essential to life. These are the carbohydrates, lipids (or fats), proteins, and nucleic acids. All of the major macromolecule classes are similar, in that, they are large polymers that are assembled from small repeating monomer subunits. In Chapter 6, you were introduced to the polymers of life and their building block structures, as shown below in Figure 11. 1. Recall that the monomer units for building the nucleic acids, DNA and RNA, are the nucleotide bases, whereas the monomers for proteins are amino acids, for carbohydrates are sugar residues, and for lipids are fatty acids or acetyl groups.
This chapter will focus on an introduction to the structure and function of these macromolecules. You will find that the major macromolecules are held together by the same chemical linkages that you’ve been exploring in Chapters 9 and 10, and rely heavily on dehydration synthesis for their formation, and hydrolysis for their breakdown.

Which macromolecules may behave as enzymes?
Proteins are involved in many cellular functions. Proteins can act as enzymes which enhance the rate of chemical reactions. In fact, 99% of enzymatic reactions within a cell are mediated by proteins. Thus, they are integral in the processes of building up or breaking down of cellular components. Proteins can also act as structural scaffolding within the cell, helping to maintain cellular shape. Proteins can also be involved in cellular signaling and communication, as well as the transport of molecules from one location to another. Under extreme circumstances such as starvation, proteins can also be used as an energy source within the cell.

What 4 macromolecules are enzymes?
Proteins, carbohydrates, nucleic acids, and lipids are the four major classes of biological macromolecules—large molecules necessary for life that are built from smaller organic molecules.
Now that we’ve discussed the four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), let’s talk about macromolecules as a whole. Each is an important cell component and performs a wide array of functions. Combined, these molecules make up the majority of a cell’s dry mass (recall that water makes up the majority of its complete mass). Biological macromolecules are organic, meaning they contain carbon. In addition, they may contain hydrogen, oxygen, nitrogen, and additional minor elements.
Dehydration Synthesis. Most macromolecules are made from single subunits, or building blocks, called monomers. The monomers combine with each other using covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts. This type of reaction is known as dehydration synthesis, which means “to put together while losing water.”
In a dehydration synthesis reaction (Figure 1), the hydrogen of one monomer combines with the hydroxyl group of another monomer, releasing a molecule of water. At the same time, the monomers share electrons and form covalent bonds. As additional monomers join, this chain of repeating monomers forms a polymer. Different types of monomers can combine in many configurations, giving rise to a diverse group of macromolecules. Even one kind of monomer can combine in a variety of ways to form several different polymers: for example, glucose monomers are the constituents of starch, glycogen, and cellulose.
What are enzymes classified by?
Enzymes are actually classified into seven classes, namely oxidoreductases, transferases, hydrolases, lyases, isomerases, ligases, and translocases. The classification is related to the catalyzed reactions. This chapter presents the classification and nomenclature of these powerful biocatalyzers.

What are the 4 types of enzymes?
Enzymes are proteins composed of amino acids linked together in one or more polypeptide chains, with the primary structure determining the three-dimensional structure of the enzyme. The secondary structure describes localized polypeptide chain structures, such as α-helices or β-sheets. The tertiary structure is the complete three-dimensional fold of a polypeptide chain into a protein subunit, while the quaternary structure describes the three-dimensional arrangement of subunits.
The active site is a groove or crevice on an enzyme where a substrate binds to facilitate the catalyzed chemical reaction. Enzymes are typically specific because the conformation of amino acids in the active site stabilizes the specific binding of the substrate. The active site generally takes up a relatively small part of the entire enzyme and is usually filled with free water when not binding a substrate.
There are two different models of substrate binding to the active site of an enzyme: the lock and key model, which proposes that the shape and chemistry of the substrate are complementary to the shape and chemistry of the active site on the enzyme, and the induced fit model, which hypothesizes that the enzyme and substrate don’t initially have the precise complementary shape/chemistry or alignment but become induced at the active site by substrate binding. Substrate binding to an enzyme is stabilized by local molecular interactions with the amino acid residues on the polypeptide chain.
Why are enzymes macromolecules?
Enzymes must therefore be large enough in order to become rigid – another reason for Nature to develop biological catalysts into macromolecules. A protein molecule is also a cooperative system, in the sense that the conformation of each amino acid residue is dependent upon the conformation of all other bonds.
What are the 4 major enzymes?
The four main enzymes involved in DNA replication are DNA helicase, RNA primase, DNA polymerase, and DNA ligase.
